RING SPINNING 0R TWISTING MACHINE.

Application filed November 25, 1910.

To all whom it may concern:

Be it known that I, ALoNzo E. RHoADns, a citizen of the United States,and resident of Hopedale, county of \Vorcester, State of.

Massachusetts, have invented an Improve ment in Ring Spinning orTwisting Machines, of which the following description, in connectionwith the accompanying drawing, is a specification, like characters 011the drawing representing like parts.

This invention relates to ring spinning or twisting machines and it hasmore particular reference to the means for guiding the ring-rail in itsreciprocation due to the builder-motion, such reciprocation of thering-rail acting to lay the yarn with the proper traverse upon therotating yarn receivers or bobbins carried by the usual spindles.

In apparatus of this type the means usually employed for guiding thering-rail in its reciprocating movement is defective in that there is atendency for the rail to chatter or vibrate more or less, particularlynear the upper end of its stroke, such vibration having an objectionableeffect upon the yarn. So, too, there is some tendency of the ringrail tobecome twisted or deflected out of true.

My present invention has for its object the production of novel andefiicient means for overcoming the objections mentioned, and as willappear hereinafter the means for guiding and preventing twisting orimproper vibration of the ring-rail is entirely separate from theactuating connection between said ring-rail and the builder-motion.

I have herein shown my invention as applied to a twister of a well knowncharacter, and the novel features of my invention will be fullydescribed in the subjoined specification and particularly pointed out inthe following claims.

Figure 1 is a front elevation, partly broken out, of a portion of atwister embodying one form of my present invention, the view being takenat the power transmitting end of the frame, the builder-motion and theconnections with the ring-rail being shown; Fig. 2 is a transversesection through the frame on the line 22, Fig. 1, looking toward theleft; Fig. 3 is a horizontal sec tional detail on the line 3 8, Fig. 2,to show clearly in top-plan one of the rigid connectors between thering-rails on oppo- Specification of Letters Patent.

site sides of the frame; Fig. 4 is an enlarged sectional detail on theline t-L, Fig. 1, to be referred to.

Referring to Figs. 1 and 2 the inclosed end A of the frame, to protectthe gearing, the fixed side rails B in which the twisting spindles C arerotatably mounted, the V615 tically-reciprocating ring-rails D havingsuitable rings E, the delivery-rolls F mounted in the stands G, at eachside of the frame, on the top-board H, the longitudinally movabletraverserods I having usual guideeyes J, Fig. 2, and the spindle-drivingdrum K connected by flexible bands L with the whirls M of the spindlesto rotate the latter, may be and are all of usual construction, thedrum-shaft in practice being provided with fast and loose pulleys, (notshown).

Referring to Fig. 2 the shafts of the lower front delivery-rolls F haveusual attached gears N driven by the large intermeshing gears O, 0 oneof which meshes with the pinion P fast on the shaft of the changegear Q,driven in usual manner and carried by the radius-arm R, all of suchparts being substantially of Well known construction and forming no partof my present invention. Herein the builder-motion is actuated by asprocket-chain S driven from the shaft of one of the gears O, and whilecertain portions of the builder-motion and its actuating means form thesubj cot-matter of claims in a co-pending application Serial No. 467,252filed by me December 12, 1909, a sufiicient part of the same will beherein described to enable the operation thereof to be understood,though my present invention is not restricted in its use merely to theparticular builder-motion shown herein, as will be manifest. Saidsprocket-chain drives a gear 40 meshing with a pinion 41, see dottedlines Fig. 2, on a short shaft 42 which serves as, and also provides, afulcrum for the head &3 of a sleevebearing l l in which is mountedrotatably the transmitting shaft l?) having on one end a worm 4:6 and atits other end the bevel-gear e7 driven by a like gear 48 on shaft 42.Worm 4E6 drives a worm-gear &9 fast on the longitudinal shaft 50supported in the end A and by bracket 51, the traverse cam 52 andhand-wheel 53 being fixedly mounted on said shaft, the cam actuating thebuilder-motion, all as shown in my application referred to.

The rocker-arms S, S are attached to the transverse rock-shafts T, T,Fig. 1, and shaft T has an upturned arm T connected by a link T with asimilar arm T fast on the rock-shaft T, the latter having also thefixedly attached segment V connected by a chain V with the builderarmG7, the follower-roll 68 on the builder-arm cotiperating with thebuilder-cam 52, all in well known manner. The chain V passes over aguide-sheave V shown in Fig. 1, and the hub 76 of the builder-arm rocks011 the fulcrum-bar 7a, and as the rotating cam 52 acts upon thefollower 68 the builder-arm is oscillated, the down stroke of the latterpulling on the chain V to rock the shafts T, T and thereby elevate thefree ends of the rocker-arms S, S.

In my present invention I have dispensed with lifter-rods fixedlyattached to and depending from the ring-rail and vertically slidable inbearings on the spindle rail or other fixed part of the frame, saidlifterrods resting attheir lower ends on rolls carried by therocker-arms, as is common in apparatus of this type, and instead of suchconstruction I have provided vertical and fixed guides for thering-rail, with independent and separate lifter connections be tween thering-rail and the rockerarms. Each ring-rail D has rigidly attached toit at suitable intervals, depending upon the size and length of theframe, backwardly extended carriers, shown as brackets 1, shaped toclear the rail-flange at the back and then upturned at 2 to support ahorizontal stud 3, the bracket being prolonged toward the longitudinalcenter of the frame from the upturned part 2, to form a head. 1. Thehead 1 is provided with a heavy bearing boss or hub 5, and a second andsimilar bearing 6 in alinemcnt therewith is formed on the lower end of ahanger 7 depending from the bracket head 4 and rigidly secured to orforming an integral part of it, said alined bearings sliding upon avertical guiderod '8. Each guide-rod is seated in a holder 9 fixedlyattached to the under side of the top-board H, the guide-rod beingsecured in said holder in any suitable manner, as by a set-screw 10, andbetween the bearings 5 and 6 the guide-rod is rigidly connected with thespindle rail 13 by a brace 11 extended from the back thereof, the bracebeing laterally curved, as shown by the shading thereon in Fig. 2.

By the means described each guide-rod is held fixedly in verticalposition by direct connections with the main frame, so that thering-rail D is guided in a true vertical path during its reciprocatingmovement, the bearings 5 and (3, which are fixed with relation to thering-rail, embracing the guiderod above and below, respectively, thebrace 11 and sliding upon said guide-rod. As said bearings 5 and Gcoiiperate with the guiderod at quite widely separated points, oneadjacent the ring-rail and the other at a considerable distance belowthe spindlerail B, it is impossible for the ring-rail to be deflectedlaterally between or adjacent the several guide-rods. Furthermore, asthe bearing 5 is fixed with relation to the ringrail and is adjacentthereto no chattering or vibration of the rail can occur at any point ofits traverse, for the guide-rod 8 laterally sustains and guides thebearing 5 at all points of the traverse. The two ring-rails reciprocatein unison, and to still further stilfen them and prevent any tendency ofthe rails to twist out of true horizontal planes 1 connect them atintervals by rigid connectors. Herein each bracket head 4: has bolted toit the foot 12 of an upright ear 13, and as shown in Fig. 3 the ears arelaterally offset from each other, to cooperate with a rigid arched baror connector 14, cut out at its ends on opposite sides to receive theears, clamping bolts 15 passing through said ears and the contiguousends of the connector to rigidly unite the parts.

To accommodate any slight irregularities in the several castings Iprovide the ears and the ends of the connector 1 1 with slots 16 for theshanks of the bolts, the latter being set up by suitable nuts 17, asclearly shown in Figs. 2 and 3. Thus the two ringrails are rigidlyconnected to move as a unit, each rail serving to stiffen and brace theother, and in a measure each ring-rail thus is guided in its verticalreciprocation not only by its sliding connection with its own series offixed guides 8 but also by the fixed guides for the other rail, so thatthe traverse movement of each ring-rail is smooth and even and whollyfree from vibration or chattering at any time.

Lifter rods 18 are pivotally mounted at their upper ends on the studs 3,and each lifter rod has at its lower end a hub 19 which loosely embracesthe shank of a headed pivot-pin 20, Fig. 4, reduced in diameter to leavea shoulder 21 which bears against a collar 22 surrounding the pinbetween the hub 19 and the enlarged end 23 of the rocker-arm, as S. Thisend 23 has a segmental slot 2% for the reception of the pin 20, and thelatter is clamped in adjusted position on the rocker-arm by a nut 25,the adjustment being provided so that each lifter rod 18 may beaccurately connected with its particular rocker-arm. When the nut is setup the end 23 of the rocker arm is clamped between the collar 22, andthe nut, with the pivot-pin 20 in the desired adjustment, the hub 19rocking freely on the pin as the rocker-arm swings up and down duringthe traverse.

From the foregoing description and the drawings it will be seen that thebuilder-motion effects the vertical reciprocation of the ring-rails byor through the lifter rods 18, and it will be clear that the latter areentirely independent of and separate from the means for guiding thering-rails in their reciprocating movement.

Inasmuch as the lifter rods 18 have some slight lateral movement aboutthe studs 3 as centers the guide-rod braces 11 are laterally curved, ashereinbefore referred to, to permit such movement. Each lifter rod actsupon the ring-rail adjacent one of its bearings 5 which slides on theguide-rod 8, and any tendency of a lifter rod to twist or distort thering-rail is counteracted and prevented by the adjacent rigid connectionwith the opposite ring-rail. As a matter of fact the action of thebuilder-motion is transmitted directly by the lifter-rods to theopposite and rigidly-connected pairs of railcarrying brackets 1, and asthese brackets are positively guided in fixed vertical paths of movementand support the ring-rails the latter are practically relieved from anyfunction beyond that of carrying the rings and effecting the traversethereof. By this construction and arrangement I obviate any directstrain upon the ring-rail from the action of the builder-motion, and theoperation of the machine as a whole is greatly improved.

I have shown and described herein the most satisfactory practicalembodiment of my invention now known to me, but the same may be variedor modified in different details of construction and arrangement bythose skilled in the art without departing from the spirit and scope ofmy invention as set forth in the claims hereunto annexed.
